Endoscopic airway management of acute upper airway obstruction

摘要

The conventional treatment for patients with acute upper airway obstruction is tracheostomy, which is a safe, definitive procedure in most hands. Alternatively, a debulking procedure can be considered but this requires both surgical and anaesthetic skill and expertise. However, where possible, it provides a good alternative with the advantages of removing the cause of obstruction and yielding tissue for histopathological analysis, and avoiding the need for a tracheostomy, with its associated morbidity. We evaluated all patients who presented with acute upper airway obstruction and underwent endoscopic laser debulking surgery performed by the senior author, over a three and a half year period. We recorded patient demographic data, their underlying pathologies, complication rates associated with laser debulking surgery and the conversion to tracheostomy. Thirty patients were identified, including 19 males and 11 females, with a mean age of 57.10 ± 17.20 years (19-93 years). All patients underwent debulking procedures with carbon dioxide laser under general anaesthetic. All patients had their underlying diagnosis confirmed from their debulking surgery. Twelve patients were found to have benign pathology and 18 had malignant airway obstruction. There were no laser-associated complications. One patient required conversion to emergency tracheostomy, during their debulking surgery. Endoscopic laser assisted debulking surgery has successfully been used to establish a safe airway. It allows obtaining tissue specimens, to confirm the underlying diagnosis, thus avoiding the need for further biopsies under anaesthetic. For all malignant cases, patients were subsequently able to proceed to definitive treatment. It has obviated the need for emergency tracheostomy in almost all of the cases in our patient cohort.
